Rovers boss Tony Mowbray has revealed that Charlie Mulgrew, Marcus Antonsson and Ben Gladwin have all returned to training ahead of Saturday's game against Oldham.
The trio have been sidelined in recent weeks but now could be in contention for a place in the squad for this weekend's league match at Ewood Park.
Speaking in Thursday's pre-match press conference, Mowbray says their respective comebacks are a timely boost as his side prepare for the last 16 games of the season.
"A few have been training today," he said. "Charlie trained today and has every chance of playing if he's fit; Marcus and Ben too, but we'll wait to see how they are.
"Harry Chapman wasn't training with us, but he was out there on the grass today too. They're coming back, they're on their way, and you can feel the positive vibe in training.
"Darragh Lenihan will hopefully get 90 minutes for the Under-23s tomorrow [against Reading] and then he'll be ready for us as well.
"There are a lot of positives but, regarding the squad, I'll wait to see what the medical department say tomorrow.
"We'll then pick the squad for Saturday, pick the team and hopefully get a result against Oldham. It's getting more difficult every week now!
"Corry [Evans] is now chomping at the bit too, and the emergence of the likes of [Lewis] Travis and [Joe] Nuttall makes competition even tougher.
"You can only play 11 players and you have to find the right balance, hopefully we'll get that this weekend."
